Use Github OAuth token to authenticate into internal systems

Hello Github community.
I’m running AWX (ansible tower) which supports Github Oauth login. This works fine via an UI.
What I’m wondering now is:

I have the github app that has this token:<installation_id>/access_tokens, but this is not a Bearer token that I can send to awx. How can I achieve this?

I just want to authenticate my bot basically on awx.
